DISPOSABLE HUMIDIFIER FOR USE WITH TOBACCO PRODUCTS INCLUDING SEMI-PERMEABLE ONE-WAY MEMBRANE

摘要

A disposable humidifier (10) for use with tobacco products comprises a moisture-releasing element (12) that emits water vapour and a semi-permeable one-way membrane (14) that encloses the moisture-releasing element and transmits water vapour from the moisture-releasing element and substantially blocks the passage of water vapour and liquid water to the moisture-releasing element. The humidifier may also have an outer layer that is impermeable to water vapour and which is removed or breached before use of the humidifier in a package or container of tobacco product. The humidifier may be incorporated into the package.
